Designed for robust signal acquisition in industrial automation, the Beckhoff KL1408 Bus Terminal provides eight 24 V DC digital input channels in a compact form factor. It integrates seamlessly into Beckhoff’s modular Bus Terminal system, giving PLCs and control cabinets a cost-effective way to expand discrete I/O with clear status indication via integrated LEDs.

Optimized for fast and reliable field wiring, the KL1408 uses 1-wire connection technology with spring-actuated terminals for secure connections and quick installation. A typical 3 ms input filter ensures clean switching behavior and debouncing across machinery and process signals. The terminal conforms to EN 61131-2 (type 1/3) with defined 0 and 1 signal voltage ranges and offers 500 V isolation between K-bus and field potential. With IP20 housing, EMC conformity per EN 61000-6-2/-6-4, and approvals including CE, UL, ATEX and IECEx, it is well suited for control panels and machine building on standard 35 mm DIN rails.

Whether you are scaling PLC I/O for OEM equipment or upgrading existing control cabinets, the KL1408 delivers dependable digital input performance, streamlined installation, and broad standards compliance—advantages further reinforced by a 1-year warranty that supports confidence from commissioning through daily operation.
